I wonder where the JC Bass' stock Electrar p'up stands in an A/B frequency shape test w Dark Stars, or the original Alembic innovations?

Has anyone out there put a Dark Star on a current model, Epi, Casady Bass? With what results?

It would seem that it's 34" scale would yield an even more formidable, unqiue low end then the 30" scale Guild SF Bass II Jack was using.

I'm aware of the (tube OD) involved w the Versatone amp. I have the schematic of my current JCB..looks like it was designed to employ a passive RLC notch filter to replicate the notch created by the extreme end placement of the Alembic pickups, as well as the stereo separation involved in its sound.

nope, the Vari-Tone is wired into the circuit in place of the traditional tone cap. adjusting the regular tone knob works as usual. adjusting the knob on the Vari-Tone selects the cap value that is being utilized by the standard tone knob

Since the DS pickups are both hi-impedance, & have no preamp/notch filter built onto them, I find that there are plenty of good preamp circuits & schematics out there to (possibly)add onto this bass arrangement. (I've been building my own pedals for quite a while now.)

The Boscorelli Stompbox Cookbook has a neat passive notch filter that is continuously tuneable via a pot - it's based around a 250K, dual-gang pot, wired in conjunction w 2 resistors & 2 capacitors..obviously very tweakable & tuneable. I would consider building one of those in if I used the Dark Star.

I did have the idea of placing the DS just ABOVE the stock Electrar pickup - hence, even deeper low end. I wonder if this is even necessary, tho -
